Abstract
The present invention is a limb bolt assembly for a recurve bow. The recurve bow has an upper limb, a lower limb, and a center riser with an upper end and a lower end each having a U-shaped slot for receiving a proximal end of a respective one of the upper and lower limbs. The limb bolt assembly includes an elongated threaded bolt mounted across the U-shaped slot, an index plate for indexing a rotational position of the bolt, a sleeve located inside the U-shaped slot and threadedly engageable with the elongated bolt and further engaging with the proximal end of the respective one of the upper and lower limbs, an end attached to the end of the bolt, and a plug mounted at a bottom opening of the U-shaped slot. The sleeve has an enlarged flange with straight rim portions for engagement with the inside sidewalls of the U-shaped slot from rotating inside the U-shaped slot, so that the sleeve can be driven along the bolt by rotating the bolt to adjust the poundage and tiller of the recurve bow. The limb bolt assembly further includes positive locking members for locking the bolt to prevent it from rotating after adjustment.
